# MySQL {#mysql}
2020-03-30 12:48:55 +00:00
Permet de se connecter à des bases de données sur un serveur MySQL distant et `INSERT` et `SELECT` requêtes pour échanger des données entre Clickhouse et MySQL.
Le `MySQL` moteur de base de données traduire les requêtes sur le serveur MySQL afin que vous puissiez effectuer des opérations telles que `SHOW TABLES` ou `SHOW CREATE TABLE`.
Vous ne pouvez pas effectuer les requêtes suivantes:
- `RENAME`
- `CREATE TABLE`
- `ALTER`
## La création d'une Base de données {#creating-a-database}
2020-03-30 12:48:55 +00:00
``` sql
CREATE DATABASE [IF NOT EXISTS] db_name [ON CLUSTER cluster]
ENGINE = MySQL('host:port', ['database' | database], 'user', 'password')
2020-03-30 12:48:55 +00:00
```
**Les Paramètres Du Moteur**
- `host:port` — MySQL server address.
- `database` — Remote database name.
- `user` — MySQL user.
- `password` — User password.
## Types De Données Soutien {#data_types-support}

| MySQL | ClickHouse |
|----------------------------------|--------------------------------------------------------------|
| UNSIGNED TINYINT | [UInt8](../../sql-reference/data-types/int-uint.md) |
| TINYINT | [Int8](../../sql-reference/data-types/int-uint.md) |
| UNSIGNED SMALLINT | [UInt16](../../sql-reference/data-types/int-uint.md) |
| SMALLINT | [Int16](../../sql-reference/data-types/int-uint.md) |
| UNSIGNED INT, UNSIGNED MEDIUMINT | [UInt32](../../sql-reference/data-types/int-uint.md) |
| INT, MEDIUMINT | [Int32](../../sql-reference/data-types/int-uint.md) |
| UNSIGNED BIGINT | [UInt64](../../sql-reference/data-types/int-uint.md) |
| BIGINT | [Int64](../../sql-reference/data-types/int-uint.md) |
| FLOAT | [Float32](../../sql-reference/data-types/float.md) |
| DOUBLE | [Float64](../../sql-reference/data-types/float.md) |
| DATE | [Date](../../sql-reference/data-types/date.md) |
| DATETIME, TIMESTAMP | [DateTime](../../sql-reference/data-types/datetime.md) |
| BINARY | [FixedString](../../sql-reference/data-types/fixedstring.md) |
Tous les autres types de données MySQL sont convertis en [Chaîne](../../sql-reference/data-types/string.md).
[Nullable](../../sql-reference/data-types/nullable.md) est pris en charge.
## Exemples D'utilisation {#examples-of-use}

Table dans MySQL:
``` text
mysql> USE test;
Database changed
mysql> CREATE TABLE `mysql_table` (
-> `int_id` INT NOT NULL AUTO_INCREMENT,
-> `float` FLOAT NOT NULL,
-> PRIMARY KEY (`int_id`));
Query OK, 0 rows affected (0,09 sec)
mysql> insert into mysql_table (`int_id`, `float`) VALUES (1,2);
Query OK, 1 row affected (0,00 sec)
mysql> select * from mysql_table;

Base de données dans ClickHouse, échange de données avec le serveur MySQL:
``` sql
CREATE DATABASE mysql_db ENGINE = MySQL('localhost:3306', 'test', 'my_user', 'user_password')
```
``` sql
SHOW DATABASES
```
``` text
┌─name─────┐
│ default │
│ mysql_db │
│ system │
└──────────┘
```
``` sql
SHOW TABLES FROM mysql_db
```
``` text
┌─name─────────┐
│ mysql_table │
└──────────────┘
```
``` sql
SELECT * FROM mysql_db.mysql_table
```
``` text
┌─int_id─┬─value─┐
│ 1 │ 2 │
└────────┴───────┘
```
``` sql
INSERT INTO mysql_db.mysql_table VALUES (3,4)
```
``` sql
SELECT * FROM mysql_db.mysql_table
```
``` text
┌─int_id─┬─value─┐
│ 1 │ 2 │
